Abstract

A method for treating powder in a process in which a powdery layer is formed on a web (4) having a first side (4a) and a second side (4b) by utilizing electric forces in such a manner that at least one electrode is located at the first side (4a) of the web, at least one electrode is located at the second side (4b) of the web, and the electrodes at different sides are in different potentials. The powdery layer is recovered from the web by utilizing electric forces (2a, 2b).
